The new version of Firefox spits out a lot of errors when trying to view a page with Three.js WebGPU and TSL modules. This is true for both Windows and MacOS versions of Firefox 145.

The error is: TypeError: this.cNode.getNodeType is not a function

You can try it yourself with the TSL examples on the [three.js examples](http://threejs.org/examples) website.

Does anyone have a workaround or fix?

Thanks for the link.

Firefox Nightly does work fine with Three.js WebGPU and TSL, so I guess it’ll solve itself eventually.
